Partial sequence alignment of the 16 s rDNA variable V9 and universal U6 regions of H. pylori isolates from Egyptian patients that are 100% homologous among H. pylori ATCC 43504 and H. pylori NCTC11637 reference strains. Dots indicate the identity with the reference strains and letters indicate the base substitution. Isolates specify three individual 16S rDNA V9 alleles (signature sequences) at positions 1239–1260 (Escherichia coli nomenclature (DSRG (DNA Sequencing Research Group) n.d.))
